Munster scrum-half Murray laid on Robbie Henshaw's try while Sexton booted Ireland's other 14 points at the Aviva Stadium, leaving Wales and Cardiff between Joe Schmidt's men and a European clean sweep.

"They are quality players: Conor and Johnny have proven they are world-class," said Zebo.

"Playing out wide it can be really easy I suppose because you know what they're going to do and when they're going to do it.

"Joe Schmidt has a great game plan and those two boys are more than capable of executing it."

Henshaw's vital try on Sunday owed much to Murray's cleverly-disguised box-kick, that caught Alex Goode just out of position, allowing the Ireland centre the half-yard to claim the hoisted ball and dot down.

Racing Metro fly-half Sexton again dominated proceedings through his tactical aerial assault, ranging from high bombs to inch-perfect touch-finders.

The British and Irish Lions half-back pairing continue to set Ireland's relentlessly accurate tactical standards, the perfect lieutenants for taskmaster head coach Schmidt.

The debates would rage long on whether Murray and Sexton are the globe's peers in their respective positions, but as a duo Ireland's half-backs currently seem to have little equal.

Zebo also hailed Connacht centre Henshaw's part in the try that sent Ireland into a 16-point lead.

"It was an unbelievable score: Robbie is a classy player," said Zebo.

"He called for that ball and was clever enough to know that the advantage was there, but it was also a touch of class again from Conor, putting it right on the money.

"It was two quality pieces of play from two quality players."

Boss Schmidt has been at pains to play down any Grand Slam talk in the wake of Ireland equalling their best-ever winning run of 10 Tests.

Zebo admitted the former Leinster coach is right to shift the focus off the ultimate prize and on to the March 14 clash against Wales in Cardiff.
